ing the principle which I have discovered, as

applied to antenna systems, it will be under- .U stood that it may likewise be used in various other embodiments.

With these objects and such other objects as mayhereinafter appear, in View, I have devised the particular arrangement of parts i'hereinafter set forth and more particularly pointed out in the claims appended hereto.

Referenceis to be had to the accompanying drawing, forming a part hereof in which n AFigure 1 is a diagrammatic view illustratv ing one embodiment of a structure of my antenna system; V

Throughout the various views of the draw-` l ing, similar reference characters designate similar parts. f Inthe embodiments of my invention disclosedfin the accompanying drawing, I have shownseveral illustrative forms of my invention. It is possible to utilize my improved structurein many ways, and accordingly, it

5 will be` understood that the embodiments shown in the drawing are merely illustrative of several of the many forms of which my structure is capable of being made.

Referring now to the structure disclosed in Figures l and 2. Here is shown at l a permanent horseshoe magnet of the well known type. This may be maintained on any suitable support,'not shown, and preferably one which will permit the magnet to be moved longitudinally in the directions indicated by ou the arrows a. If desired also, the "magnet may be rotated about its longitudinal axis or it may be universally mounted to permit its movement in any direction. The magnet l is provided with the conventional poles 2 and 3 between which is disposed a metallic bar 4 or some other metal object or article possessing high conductivity or permeability. In place of a solid metallic bar or other solid conducting object, it may be found desirable to use a bar, sheet or plate composed of 'a series of layers orlaminae, two examples of which are disclosed in Figures 4 and 5. In .Figure 4 the bar 1l is oneV which is composed of numerous layers 11a which may if desired be made `75 of materials having different degrees of conductivity, such as iron, copper, brass, aluminum, etc. In such case it may be found desirable to physically separate these layers, either by an air space or by insulating sepa rators 12a (Figure 5). Such separators may be of any suitable insulation such as cloth, wood, hard or soft rubber .or .the like.

The bar 4 whether of single or multiple layers may be arranged to be shifted between the S5 poles 2 and 3 in the directions indicated by the arrows b and may also be arranged to be moved along its own and the longitudinal axis of the magnet l. The bar or other member 4 is preferably provided-with a means for re- 9*? ceiving a lead-wire, such as a binding post 5' whichreceives the end of a lead wire 6 that connects 'to the usual antenna 7 or to any object or article acting as an antenna.

Y,At 8 is' shown a bar of single or multiple 95 construction as described in regard to the bar 4, or some other object capable of actngas conductor for the radio circuit. This bar is maintained in such a position that it extends across the poles 2 and 3 of the magnet and 100 with a bindingposjt 9which receivesvtheend of a wire connection :lOthat .extends andcon, nects to the antenna binding post of a radio set. rIhe bar 8 is so mounted that it 'may be and from the poles 2 and 3 of the magnet as indicated by the arrow c. desired be shifted so that it will lie angularly with respect to the poles2-and`f3ofthe mag f net. The baiS is provdedmwith a binding post 9;which receives' a wire lead 10. that extends from the radio set bindino ost. Iliave c: found thatb r irovidinv a suitable air a i s 1 between two conductors such as, the members l4 and 8 inA an antenna lead-in and disposing While .the magnet 1 is shown to be of thev permanent horseshoe type, it will Vbe apparent that thesame may readily be of theelectro type. y

In Figures Sand 4, I show ainodilication of my device wherein I discloseapermanent. horseshoek type magnet 12 secured upon any.

support such as at 30, and preferably lrotata bly mounted as onaspindle31 or else it mayv be universally mounted so, that it may be.k

Through the structure just described and disclosed in detail in Figures 3 and 4, a variation in antenna capacity is readily had by adjusting the position of the magnet with respect to the plates 14 to 20 inclusive and 70 by adjusting the position of the bar 17 relative to ,theplates andto thefpoleshnf the magnet. 4 AVarious degrees sofl adjust-,ability and regulation of the parts described can be 7 IifnF-igiire anis-.shown a pair of opposed magnets 36 and 37, the poles of one magnet facing and separated from those on the other.

.cording1y, I do not limit myself to the several embodiments described but consider as my invention any structure coming within the scope of the annexed claims.

What I claim is:

1. In an antenna system for radio receiv ing sets, an antenna adapted for .connection to a receiver intended forthe reception of broadcast sounds, a fixed gap located in the antenna and interrupting the continuity' thereof, a magnet of t e permanent type so arranged relative to the antenna gap that the magnetic flux of the magnet is dis osed therein to bridge the gap and intensi y the received signal.

2. In an antenna system for radio receivers, an antenna adapted for connection to a radio receiver, a fixed gap located in the antenna and interrupting the continuity thereof, one or more magnets having their poles directed toward the gap whereby the magi netic flux between the poles acts to bridge the gap and intensifies the received signal.
